In the arcade cabinet's data, there are references to a secret character named "SAKE", though it is simply Yoshimitsu's model using Jin's move set.

Katsuhiro Harada has gone on to say that SAKE was originally planned for the game as an additional animal character, however SAKE was actually a salmon. No matter if the players punched or kicked, the salmon would simply flop around and make a flapping noise. This was removed as they were concerned that players would be angry about spending 100 Yen to play as a fish that can't do anything.

There were also plans for another character named INSECT, who would be a giant praying mantis. This is because there was a bug in the program which would make characters arms, legs and waists appear incredibly skinny, and they looked like a praying mantis. The idea was dropped as there weren't enough resources, what with adding so many other new characters.
